Surface Mount Transient Voltage Suppressors (TVS)

P4SMA Series

6.8 To 600 V

400W

Uni-directional

Bi-directional

Description

The P4SMA series is designed specifically to protect sensitive electronic

equipment from voltage transients induced by lightning and other transient

voltage events.

Features

For surface mounted applications in order to optimize board space

Low leakage

Uni and Bidirectional unit

Glass passivated junction

Low inductance

Excellent clamping capability

400W Peak power capability at 10 × 1000µs waveform Repetition rate

(duty cycle):0.01%

Functional Diagram

Fast response time: typically less than 1.0ps from 0 Volts to V_BRmin

Typical I_Rless than 5μA above 12V.

High Temperature soldering: 260°C/40 seconds at terminals

Typical maximum temperature coefficient ΔV_BR= 0.1% ×

V_BR@25°C× ΔT

Bi-directional

Cathode

Anode

Plastic package has Underwriters Laboratory Flammability 94V-0

Matte tin lead–free Plated

Uni-direction

Halogen free and RoHS compliant

Typical failure mode is short from over-specified voltage or current

Whisker test is conducted based on JEDEC JESD201A per its table

4a and 4c

Applications

TVS devices are ideal for the protection of I/O interfaces, V_CC

bus and other vulnerable circuits used in Telecom, Computer,

Industrial and Consumer electronic applications.
